This morning was rainy with a stiff headwind, gusting to 15 MPH out of the north. I cheated and rode to the bus. It continued sprinkling throughout the day, and I don't think it ever really let up. Only one other two-wheeled rider showed up in the parking garage this morning. He was in full business attire, covered in a gore-tex get-up.
My forward lighting setup. Especially when it's raining, I use as much light as I can, including my reflective vest.
Of course, once I got home, it was an entertaining game of "dry and clean the bike and drivetrain" while my grimy shoes were drying off.
